Abstract
The effect of solvent salt cation, temperature of electrolysis, and cathodic deposition potential to basic characteristics of uranium dioxide potentiostatic electrodeposition (cathodic current efficiency, current density, and product deposition rate) in electrolyte system M2WO4-M2W2O7-UO2WO4 (M = Li, Na, K, Cs) was studied in air. A conclusion was made that optimum electrodeposition and production of deposits not contaminated with supporting electrolyte decomposition products need higher cathodic polarization close to the solvent decomposition potentials and higher temperatures (up to 900°C). A melt based on K2WO4 was selected as the electrolyte providing satisfactory electrodeposition parameters of uranium dioxide with the composition close to stoichiometric.
